Resumo: | The yield of common bean crop is affected by high air temperature during the reproductive phase. The experiment was carried out in pots and in growth chambers (phytotron) with controlled air temperature and humidity. The objective of this study was to identify the most appropriate substrate for common bean grown in pots and to evaluate common bean genetic variability for tolerance to high air temperature during the pre-flowering (R5) to pod formation (R7) phase. To identify the most appropriate substrate two experiments were carried out in a greenhouse during 2005, with the TPS Nobre common bean cultivar. Seven substrates were evaluated: Plantmax®, carbonized rice husks, vermiculite, sand, carbonized rice husks + 20% of Plantmax®, carbonized rice husks + 20% of vermiculite and carbonized rice husks + 20% of sand. The experimental design was a completely randomized with five replications. To evaluate the genetic variability under high temperature the experiment was conducted in phytotron, with controlled temperature, lighting and photoperiod and all other conditions for growing were optimum. During the R5-R7 phase, plants were submitted to air temperature of 30°C during one hour a day. The experimental design used was completely randomized with three repetitions, with 20 common bean cultivars. In the substrate evaluation, it was possible to observe chemical and physical characteristics among the substrates. The substrate Plantmax® provided the most appropriate characteristics leading to the best conditions for growing and development of common bean plants. The cultivars showed different us in phonological, reproductive, yield traits and components indicating genetic variability for tolerance to high temperature during the reproductive phase (R5 to R7). Cultivars Pérola, TPS Bonito, BRS Valente and Corrente were tolerant to the air temperature of 30°C during one hour a day during the reproductive period. |

A avaliação dos danos causados as estruturas reprodutivas são melhor realizadas em câmara controlada (fitotron), com controle de temperatura e de umidade. Sendo assim, foram objetivos desse trabalho: (1) identificar o substrato mais apropriado para o cultivo de feijão em vasos; (2) avaliar a variabilidade genética do feijão para tolerância a alta temperatura do ar, durante o período de pré-floração (R5) à formação de vagens (R7). Para identificar o substrato mais adequado foram conduzidos dois experimentos em casa-de-vegetação, durante o ano de 2005, com a cultivar de feijão TPS Nobre. Sete substratos foram avaliados: Plantmax®, casca de arroz carbonizada, vermiculita, areia, casca de arroz carbonizada + 20% Plantmax®, casca de arroz carbonizada + 20% vermiculita e casca de arroz carbonizada + 20% areia. O delineamento experimental utilizado foi inteiramente casualizado, com cinco repetições. A avaliação da variabilidade genética para a alta temperatura do ar foi realizada em fitotron, com controle de temperatura, luz, fotoperíodo e demais condições ótimas de cultivo. Durante o subperíodo R5-R7 às plantas foram submetidas à temperatura de 30oC, durante uma hora diariamente. O delineamento experimental utilizado foi o inteiramente casualizado, com três repetições, e avaliaram-se 20 cultivares de feijão. Na avaliação de substratos, foi possível observar diferenças químicas e físicas entre os substratos. A utilização do substrato comercial Plantmax® propiciou melhores condições para o crescimento e o desenvolvimento das plantas de feijão, devido as características químicas e físicas mais apropriadas. As cultivares de feijão apresentaram comportamento diferenciado quanto à fenologia, caracteres reprodutivos e componentes da produção evidenciando a presença de variabilidade genética para tolerância a alta temperatura do ar durante o período reprodutivo (R5 a R7). As cultivares Pérola, TPS Bonito, BRS Valente e Corrente são tolerantes a temperatura do ar de 30oC, por uma hora, durante o período reprodutivo.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaPhaseolus vulgaris L.Cultivo sem soloSolução nutritivaFitotronAbortamento de floresSeleção de cultivaresPhaseolus vulgaris L. soilless croppingNutrient solutionPhytotronFlower abortionCultivar selectionCNPQ::CIENCIAS AGRARIAS::AGRONOMIASubstratos para cultivo de feijão e tolerância a alta temperatura do ar no período reprodutivoSubstrates for cultivation of common bean and tolerance to high air temperature during the reproductive phaseinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRibeiro, Nerinéia Dalfollohttp://lattes.cnpq.br/5569596745457696Medeiros, Sandro Luis Petterhttp://lattes.cnpq.br/3944438250614221http://lattes.cnpq.br/8279915841443821Hoffmann Junior, Leo5001000000094005003005002a458fb6-a362-4ab4-9102-0816600d6c8b56711376-d24c-4a52-adcc-c0dd22ce911638445538-aeac-4911-b26a-c3b65d0dfe29info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALLEO HOFFMANN.pdfapplication/pdf127845http://repositorio.ufsm.br/bitstream/1/4959/1/LEO%20HOFFMANN.pdf44df1584de8406c4fbd6f9acad32bf69MD51TEXTLEO HOFFMANN.pdf.txtLEO HOFFMANN.pdf.txtExtracted texttext/plain78686http://repositorio.ufsm.br/bitstream/1/4959/2/LEO%20HOFFMANN.pdf.txt8d35b488af6dd1ca78896a36e0fc210eMD52THUMBNAILLEO HOFFMANN.pdf.jpgLEO HOFFMANN.pdf.jpgIM Thumbnailimage/jpeg4963http://repositorio.ufsm.br/bitstream/1/4959/3/LEO%20HOFFMANN.pdf.jpg31d62a7d3066e7e11f41e6858e8cc850MD531/49592023-01-06 15:05:23.553oai:repositorio.ufsm.br:1/4959Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-01-06T18:05:23Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
